SPECIFICATION forming part of Letters Patent No. 754,801, dated March 15, 1904. Application tied November 2, 1993. Serial-No. 179,582. (No nit-fiel.)

To @ZZ whe/n it may concern:

Be itknown that I, SANFORD Poiiizoi', a citizen of the United States, residing at Byron, in thecounty of Olmsted and State of Minnesota, have invented new and useful Improvements in Cistern-Tops. of which the following is a specification.

My invention relates to improvements in cisterns, more especially to tops therefor.

It has for its object to afford an effective means of protection or guard tothe entrance of a cistein receiving water via thehousepipe or spouting and to pro 'ide for the exclusion of extraneous or foreign substance from the cistern.

Said invention consists of the detailed construction and arrangement of parts substantially as hereinafter more fully disclosed, and speeiiically pointed ont by the claims concluding the following specification.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure l is a vertical section. Fig. 2 is a Section on the line 2 2, Fig. 1.

1n the carrying out of my invention I employ a receptacle 1, which may he a tile or cylinder of earthenware or terracotta, with its lower or bottoni end especially formed with a lateral enlargement or flange l, the purpose of which will presently appear. Said cylinder or receptacle has near its upper end a lateral pipe-inlet '2 for connection with the house pipe or spout to deliver the water thereinto, it thence passing from the latter into the cistern. Also opening laterally tlirongh said cylinder, near its bottom or lower end, is an overiiow-pipe The upper end ofthe cylinder or receptacle 1 is stepped, providing it at that point with an inner shoulder or ledge 4 to permit of the application thereto of an inner or supplemental cover 5, if it is desired to use4 such, in addition to the inain or outer cover t` 4 to more eii'eetually guard against the entrance to said cylinder or receptacle, consequently to the cistern, of any foreign or iinsanitary matter.

In Aarranging or placing thepart or top 1 in position its bottom or fianged end ]fis caused to rest upon the upper end of the cistern 7, having a lateral ange 7" thereon particularly for that purpose the iange 7,how' ever, extending -ome distance vbeyond the plane of the f1: :ge 1 of part 1. Upon the projecting part of the liange '7? is'la'id a course or layer of bricks 8, abutting the liange 1, 55

and upon t-lie flange 1 is laid a like course oi" layer ot bricks f), abutting the part l and overlying or breaking joints with the. fiange 1" and the layer or course ot' bricks 8, as shown.

rI`hus it will be noted that the part or top l is secured or keyed in position upon the cistern with an effective joint-closure. the purpose of whicliis apparent.

' Having thus described iny iuveiit-ioii, what I claim as new, and desire to-secure by Letters 1. A device ofthe character described for eisterns, embracing a cylinder' having around its lower end a lateral enlargement or flange,

said cylinder or i'eceptacle havingI an inner 70 shoulder at its upper end, and an inner, andan outer, cover, said inner cover being applied to said inner shoulder and the top cover applied over all.

Q. A device of the character described for Y ciSternS, comprising a cylinder having near its upper end, an inlet connecting with the liouse 'pipe or spout and, near its lower end,

an overllowlpipe, said cylinder having, at its lower end, a lateral'enlargement or ange, 80

and, at its upper end, an iiinei'l shoulder, for

the application thereto of an inner cover, 'an

referred to, a layer of masonry placed on the 90 latter flange, and a second masonry layer overlying or breaking joints with said iirst-referred-to flange and masonry layer.

Iii testimony whereof I have signed my naine to this specilication in the presence ot' two sub- 9 5 scribing witnesses. A
